Smart glasses usually include a frame and temples, and the temples have a foldable function, that is, the temples are rotatably connected to the frame through hinges, the hinges are fixed on the frame, and the temples are rotatably connected to the hinges through a rotating shaft. The motherboard, battery, etc. of smart glasses will generate a lot of heat during use, which needs to be dissipated in time. However, due to the heat dissipation structure of existing smart glasses, it is impossible to pass through the hinges and dissipate the heat on the frame in time, resulting in excessive temperature rise at the frame, affecting the normal use of smart glasses.

[0015] Optionally, in an embodiment of the present invention, at least two heat-conducting pipes are arranged at intervals along the axis of the sleeve, and the two heat-dissipating pipes are arranged on both sides of the heat-dissipating pipe.

[0019] Optionally, in one embodiment of the present invention, the heat dissipation structure further includes a sealing sleeve, which is arranged between the first heat-conducting member and the second heat-conducting member to seal and connect the first heat-conducting member and the second heat-conducting member, and the sealing sleeve is provided with a through hole connected to the first heat-conducting hole, and during the rotation of the second heat-conducting member, the through hole is aligned with or staggered from the second heat-conducting hole.

[0020] Optionally, in an embodiment of the present invention, the sealing sleeve is made of silicone.

[0021] To achieve the above-mentioned purpose, an embodiment of the present invention proposes a pair of smart glasses, which include a frame, temples, a hinge mechanism connecting the frame and the temples, and a heat dissipation structure.

In addition, when the hinge module is rotated to the folded state of the temples, the second heat-conducting member will also rotate synchronously, so that the second heat-conducting hole on the second heat-conducting member is staggered with the first heat-conducting hole on the first heat-conducting member, the second heat-conducting channel is disconnected from the first heat-conducting channel, and heat exchange cannot be performed between the heat source and the cold source.

[0035] It should be noted that all directional indications (such as up, down, left, right, front, back,...) in the embodiments of the present invention are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings).

[0036] In addition, the descriptions such as "first" and "second" in the embodiments of the present invention are only for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the embodiments of the present invention, "a plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

For example, "fixation" may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two components or the interaction relationship between two components, unless otherwise clearly limited.

[0038] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the embodiments of the present invention.

[0039] Currently, in the field of head-mounted display device products, most products tend to be designed as smart glasses in the form of glasses in order to reduce the weight of the products. When the main board, battery, etc. of the smart glasses are in use, a large amount of heat will be generated at the temple. For example, the power consumption of existing glasses-type AR products is 3.5-5.4W. Especially for outdoor AR glasses, the required eye-in brightness is as high as 2000 nit, and the power consumption generally reaches more than 4.5W. The large power consumption causes the temperature of the main chip to rise rapidly. If heat cannot be dissipated and cooled in time, it will cause the product to freeze. In current smart glasses, the temples and the frame are connected by a hinge module to achieve the opening or folding of the temples. However, the existing heat dissipation pipes cannot pass through the hinge module, and heat cannot be dissipated in time through convection on both sides of the hinge module, resulting in a relatively large local temperature rise of the smart glasses.

[0040] In view of this, the embodiments of the present invention provide a heat dissipation structure and a smart glass. By providing a first heat conducting member and a second heat conducting member that are rotatably connected, they can be inserted into the hinge module, and the second heat conducting member can rotate synchronously with the temple. When the temple rotates to the open state, the second heat conducting holes on the second heat conducting member are aligned with the first heat conducting holes on the first heat conducting member. At this time, the second heat conducting channel is communicated with the first heat conducting channel, and heat exchange can be carried out between the heat source and the cold source to cool and dissipate heat from the heat source in time. It can be understood that by providing a first heat conducting member and a second heat conducting member that are rotatably connected, heat exchange between the components on both sides of the hinge module can be realized, the uniformity of heat dissipation of the temple and the frame can be improved, and the local temperature rise can be prevented from being too large to affect the use.

[0041] In order to better understand the above technical solutions, the above technical solutions will be described in detail below with reference to the accompanying drawings.

[0042] As Figures 1-3 shown, a heat dissipation structure proposed by an embodiment of the present invention includes:

[0043] A first heat conducting member 100 having a first heat conducting channel, and a first heat conducting hole 111 communicating with the first heat conducting channel is provided on the first heat conducting member 100; and

[0044] A second heat conducting member 200 sleeved outside the first heat conducting member 100 and rotatably connected to the first heat conducting member 100; the second heat conducting member 200 has a second heat conducting channel, and a second heat conducting hole 211 communicating with the second heat conducting channel is provided;

[0045] During the rotation of the second heat conducting member 200, the first heat conducting hole 111 is aligned with the second heat conducting hole 211 to connect the first heat conducting channel and the second heat conducting channel; or the first heat conducting hole 111 is offset from the second heat conducting hole 211 to disconnect the first heat conducting channel and the second heat conducting channel.

[0046] In the technical solution adopted in this embodiment, the first heat conducting member 100 provided can be connected to a heat source to export the heat of the heat source, and the second heat conducting member 200 provided can be connected to a cold source, so that a cooling channel is formed between the heat source and the cold source, and heat exchange occurs between the heat source and the cold source to achieve heat dissipation and temperature reduction of the heat source. The second heat conducting member 200 is sleeved outside the first heat conducting member 100, and the second heat conducting member 200 is rotatably connected to the first heat conducting member 100, so that the heat dissipation structure can pass through the hinge module in the smart glasses. When the hinge module rotates to the state where the temple is opened, the second heat conducting member 200 will rotate synchronously, so that the second heat conducting hole 211 on the second heat conducting member 200 is aligned with the first heat conducting hole 111 on the first heat conducting member 100, thereby connecting the first heat conducting channel and the second heat conducting channel. The heat dissipated by the heat source on the temple can be transferred to the cold source on the frame through the first heat conducting channel and the second heat conducting channel, which is conducive to heat exchange between the heat source and the cold source, timely dissipating the heat of the heat source, quickly cooling the temple, and ensuring the normal operation of the smart glasses. It can be understood that through the rotatably connected second heat conducting member 200 and the first heat conducting member 100, it can pass through the hinge module to dissipate heat from the components on both sides of the hinge module, improve the uniformity of heat dissipation, and prevent the local temperature of the smart glasses from being too high. In addition, when the hinge module rotates to the state where the temple is folded, the second heat conducting member 200 will also rotate synchronously, so that the second heat conducting hole 211 on the second heat conducting member 200 is offset from the first heat conducting hole 111 on the first heat conducting member 100, and the second heat conducting channel is disconnected from the first heat conducting channel, and heat exchange cannot occur between the heat source and the cold source. It should be noted that the first heat conducting member 100 and the second heat conducting member 200 in this embodiment can be respectively tubular structures, and a coolant can be filled inside to cool down through the flow of the coolant, or can be heat pipe structures, which are not limited herein.

[0047] Specifically, the heat dissipation structure in this embodiment can be used in smart glasses, which include temples, frames and hinge modules. Among them, the hinge module connects the temples and the frame so that the temples can be opened or folded. The heat dissipation structure includes a first heat-conducting member 100 and a second heat-conducting member 200 that are rotatably connected. The first heat-conducting member 100 can be connected to a heat source on the frame, and the second heat-conducting member 200 can be connected to a cold source on the temple. When the temple is rotated to an open state through the hinge module, a large amount of heat will be emitted when the smart glasses are working. At this time, the second heat-conducting member 200 will rotate synchronously with the temple, so that the second heat-conducting hole 211 on the second heat-conducting member 200 is aligned with the first heat-conducting hole 111 on the first heat-conducting member 100, the second heat-conducting channel is connected to the first heat-conducting channel, and heat exchange can be performed between the heat source and the cold source to achieve cooling of the frame, and prevent the local temperature rise of the smart glasses from being too large and affecting normal use. In addition, when the temples are rotated to the folded state through the hinge module, the smart glasses do not work, do not generate a lot of heat, and do not need to be cooled. At this time, the second heat-conducting member 200 will also rotate synchronously with the temples, so that the second heat-conducting hole 211 on the second heat-conducting member 200 is staggered with the first heat-conducting hole 111 on the first heat-conducting member 100, and the second heat-conducting channel is disconnected from the first heat-conducting channel, and heat exchange cannot be performed.

[0048] Further, see Figures 2-3 In one embodiment of the present invention, the first heat conducting member 100 comprises:

[0049] A sleeve 110, a first heat conducting channel and a first heat conducting hole 111 are provided in the sleeve 110; and

[0050] The heat conducting pipe 120 has one end connected to the sleeve 110 and the other end extending in a direction away from the sleeve 110 . The heat conducting pipe 120 is in communication with the first heat conducting channel.

[0051] In this embodiment, the first heat-conducting member 100 includes a sleeve 110 and a heat-conducting pipe 120. The sleeve 110 is disposed in the wiring cavity of the hinge module. One end of the heat-conducting pipe 120 is connected to the sleeve 110, and the other end is connected to the heat source. It is understandable that the second heat-conducting member 200 is sleeved on the outer peripheral surface of the sleeve 110, and the interior of the sleeve 110 forms a first heat-conducting channel, and is provided with a first heat-conducting hole 111 connected to the first heat-conducting channel. The heat-conducting pipe 120 is connected to the outer peripheral surface of the sleeve 110 and is connected to the first heat-conducting channel. Specifically, the sleeve 110 and the heat-conducting pipe 120 can be integrally formed, or can be assembled in a split design, which is not limited here.

[0052] Further, see Figure 2In one embodiment of the present invention, the first heat-conducting member 100 further includes a limiting protrusion 130, which is provided at the end of the sleeve 110 and is protruded in the axial direction away from the sleeve 110. By providing the limiting protrusion 130, the sliding of the second heat-conducting member 200 in the axial direction of the sleeve 110 can be limited. The limiting protrusion 130 can be provided in multiple circumferential intervals along the end of the sleeve 110, or can be directly around the sleeve 110. It can be understood that the limiting protrusion 130 extends in the axial direction away from the sleeve 110. The structure of the limiting protrusion 130 can be triangular, rectangular or annular, which is not limited here. Preferably, the two axial ends of the sleeve 110 are respectively provided with limiting protrusions 130 to abut against the two opposite end faces of the second heat-conducting member 200 in the axial direction of the sleeve 110.

[0053] Further, see Figures 2-3 In one embodiment of the present invention, the second heat conducting member 200 comprises:

[0054] A connecting cover 210, a second heat conducting hole 211 is provided in the connecting cover 210, and the connecting cover 210 is sleeved on the outside of the sleeve 110; and

[0055] The heat dissipation pipe 220 is communicated with the second heat conduction hole 211 , and the second heat conduction channel is provided in the heat dissipation pipe 220 .

[0056] In this embodiment, the second heat-conducting member 200 includes a connection cover 210 and a heat dissipation pipe 220. Among them, the connection cover 210 is sleeved on the outside of the sleeve 110. It can be understood that the interior of the connection cover 210 is a hollow structure, and the two ends of the axial direction are open. The connection cover 210 is sleeved on the outside of the sleeve 110 and is rotatably connected with the sleeve 110. It can rotate relative to the sleeve 110 under the action of an external force, so that the second heat-conducting hole 211 on the connection cover 210 is aligned or staggered with the first heat-conducting hole 111. One end of the heat dissipation pipe 220 is connected to the circumferential surface of the connection cover 210 and is connected to the second heat-conducting hole 211. It can be understood that a second heat-conducting channel is formed on the heat dissipation pipe 220. When the second heat-conducting hole 211 is aligned with the first heat-conducting hole 111, the first heat-conducting channel is connected to the second heat-conducting channel; when the second heat-conducting hole 211 is staggered with the first heat-conducting hole 111, the first heat-conducting channel is disconnected from the second heat-conducting channel. It should be pointed out that in order to ensure that heat exchange is carried out smoothly when the first heat conduction channel and the second heat conduction channel are connected, the connection cover 210 and the sleeve 110 need to be sealed and connected.

[0057] Furthermore, in one embodiment of the present invention, at least two heat pipes 120 are provided at intervals along the axis of the sleeve 110, and two heat dissipation pipes 220 are provided on both sides of the heat dissipation pipe 220. By providing multiple heat dissipation pipes 220, the heat exchange efficiency between the heat source and the cold source can be accelerated, more heat from the heat pipe 120 can be taken away, the heat source can be cooled quickly, and the heat dissipation effect can be further improved.

[0058] Furthermore, in one embodiment of the present invention, the heat dissipation pipe 220 includes a first section and a second section that are bent and connected, and one end of the first section away from the second section is connected to the second heat conducting hole 211. In this embodiment, the first section of the heat dissipation pipe 220 is arranged in the wiring cavity of the hinge module, and the second section is bent and passes through the wiring cavity 413 to connect with the temple.

[0059] Furthermore, in an embodiment of the present invention, the heat dissipation pipe 220 and / or the heat conduction pipe 120 are rigid parts, which can prevent the heat dissipation pipe 220 and / or the heat conduction pipe 120 from bending and being unable to rotate.

[0060] Further, in one embodiment of the present invention, the rigid member is a rigid heat pipe; and / or the heat dissipation pipe 220 is connected to the connection cover 210 by welding; and / or the heat conduction pipe 120 is connected to the sleeve 110 by welding.

[0061] Further, see Figures 2-3 In one embodiment of the present invention, the heat dissipation structure further includes a sealing sleeve 300, which is arranged between the first heat-conducting member 100 and the second heat-conducting member 200 to seal and connect the first heat-conducting member 100 and the second heat-conducting member 200, and the sealing sleeve 300 is provided with a conducting hole connected to the first heat-conducting hole 111, and during the rotation of the second heat-conducting member 200, the conducting hole is aligned or staggered with the second heat-conducting hole 211. Specifically, the sealing sleeve 300 can be an annular structure, which is sleeved on the outer peripheral surface of the sleeve 110, and is provided with a conducting hole connected to the first heat-conducting hole 111, and the connecting cover 210 is sleeved on the outer peripheral surface of the sealing sleeve 300. It can be understood that by setting the sealing sleeve 300, the connecting cover 210 and the sleeve 110 can be sealed and connected, thereby improving the efficiency of heat exchange between the heat source and the cold source. Preferably, the material of the sealing sleeve 300 is silicone.

[0062] To achieve the above purpose, an embodiment of the present invention proposes a pair of smart glasses, which include a frame, temples, a hinge mechanism connecting the frame and the temples, and a heat dissipation structure, wherein the heat dissipation structure is the heat dissipation structure described above, the hinge mechanism forms a wiring cavity, and the heat dissipation structure is arranged in the wiring cavity to connect the cold source and the heat source. Specifically, the specific structure of the heat dissipation mechanism refers to the above embodiment. Since the smart glasses adopt all the technical solutions of the above embodiment, they at least have all the beneficial effects brought by the technical solutions of the above embodiment, which will not be repeated here.

[0063] In one embodiment, referring to Figure 4 , the hinge module may include a first connection component 410 and a second connection component 420. The first connection component 410 is connected to the spectacle frame, and the second connection component 420 is connected to the temple. The first connection component 410 and the second connection component 420 are connected by a rotating component 430. The rotating component 430 and the second connection component 420 are arranged outside the first connection component 410. It can be understood that the second connection component 420 can be arranged on any side outside the first connection component 410 or sleeved outside the first connection component 410. The rotating component 430 connects the first connection component 410 and the second connection component 420 and does not extend into the interior of the first connection group, so it will not occupy the wiring cavity 413 formed inside the first connection component 410, thus providing sufficient wiring space for the cable, the heat dissipation tube 220, and the flexible circuit board, facilitating the arbitrary bending and pre-bending of the cable, the heat dissipation tube 220, and the flexible circuit board when passing through the wiring cavity 413, and preventing stress on the temple. At the same time, a first inlet and a first outlet are also provided on the first connection component 410. The cable and the like extend into the wiring cavity 413 from the first inlet and pass out of the wiring cavity 413 from the first outlet. The cable and the like can be pre-bent when passing through the wiring cavity 413, facilitating the layout of the cable. It can be understood that the sleeve 110 is arranged in the wiring cavity 413, the heat conduction tube 120 enters the wiring cavity 413 from the first inlet, and the heat dissipation tube 220 passes out of the wiring cavity 413 from the first outlet.

[0064] It should be noted that referring to Figure 5, the rotating assembly 430 includes a rotating shaft 431 and a shaft hole 432. Among the first connecting assembly 410 and the second connecting assembly 420, the rotating shaft 431 is selectively arranged on one of them, and the shaft hole 432 is selectively arranged on the other. Specifically, the rotating shaft 431 cooperates with the shaft hole 432. It can be understood that one end of the rotating shaft 431 is rotatably arranged in the shaft hole 432, so that the relative rotation of the first connecting assembly 410 and the second connecting assembly 420 can be realized. Moreover, the structure of the cooperation between the rotating shaft 431 and the shaft hole 432 is relatively simple, which can simplify the production process, reduce the production complexity, and can also reduce the occupied space of the hinge module, meeting the design requirements of the product being small and lightweight. In an embodiment, the rotating shaft 431 can be arranged on the end face of the first connecting assembly 410 and extend towards the second connecting assembly 420, and the shaft hole 432 is arranged on the end face of the second connecting assembly 420 facing the first connecting assembly 410. One end of the rotating shaft 431 away from the first connecting assembly 410 is rotatably arranged in the shaft hole 432. In another embodiment, the rotating shaft 431 can also be arranged on the end face of the second connecting assembly 420 and extend towards the first connecting assembly 410, and the shaft hole 432 is arranged on the end face of the first connecting assembly 410. At this time, the shaft hole 432 is not communicated with the wire routing cavity 413 to prevent the rotating shaft 431 from extending into the wire routing cavity 413 and occupying space. That is to say, in this embodiment, the arrangement positions of the rotating shaft 431 and the shaft hole 432 are not limited, and in actual application, it can be preferably selected according to the situation.

[0065] Specifically, referring to Figure 5 , the first connecting assembly 410 includes: a first bracket 412; a cylinder 411 connected to the first bracket 412, a wire routing cavity 413, a first inlet and a first outlet are arranged in the cylinder 411, and the second connecting assembly 420 is sleeved outside the cylinder 411 and is rotatably connected to the cylinder 411;

[0066] The second connecting assembly 420 includes: a second bracket 422; and a rotating cylinder 421 connected to the second bracket 422. The rotating cylinder 421 is sleeved outside the cylinder 411 and is rotatably connected to the cylinder 411. A second inlet and a second outlet are arranged in the rotating cylinder 421.

[0067] In this embodiment, the first bracket 412 arranged can be connected to the spectacle frame, the second bracket 422 can be connected to the temple. The cylinder 411 is fixedly connected to the first bracket 412, the rotating cylinder 421 is fixedly connected to the second bracket 422, and the rotating cylinder 421 is sleeved outside the cylinder 411, so as to realize the connection of the hinge structure between the temple and the spectacle frame. Preferably, the first bracket 412 is tangent to the cylinder 411, and the second bracket 422 extends along the radial direction of the rotating cylinder 421. It should be noted that the rotating shaft 431 is arranged on the end face of the cylinder 411 facing the rotating cylinder 421, and the shaft hole 432 is arranged on the end face of the rotating cylinder 421 facing the cylinder 411.

[0068] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the embodiments of the present invention. Any equivalent structural transformation made under the inventive concept of the embodiments of the present invention by using the specification and drawings of the embodiments of the present invention, or any direct / indirect application in other related technical fields shall be included in the patent protection scope of the embodiments of the present invention.
